Macrocyclization scanning
WebHere we describe a general synthetic platform for side-chain macrocyclization of an unprotected peptide library based on the S N Ar reaction between cysteine thiolates and a new generation of highly reactive perfluoroaromatic small molecule linkers. WebAs macrocyclization reactions are often low yielding, suffering from unwanted oligomerizations, a unique double strain promoted azide cycloaddition ring closure using Sondheimer diyne 1 was developed . 5 The sequential cycloaddition of 1 with two equivalence of azide is known to produce the saddle shaped dibenzo-cycloocta-bis-1,2,3 …
